Make attachment clip mandatory while submitting request

[roomawakar]

Hi All,

I am having a requirement to make the attachment clip mandatory while submitting the request once a particular check box is selected.

Firstly, i wrote a onSubmit catalog client script with the below code but this is working on desktop view but it isn't working on the Employee Center Service Portal.

if (g_form.getValue('sbx_crr_requestType') == 'Manual Letter Generation for Address correction Requests') {

        try {

            var cat_id_return = gel('sysparm_item_guid').value;

            //alert('Happy '+cat_id_return);

            var gr = new GlideRecord("sys_attachment");

            gr.addQuery("table_name", "sc_cart_item");

            gr.addQuery("table_sys_id", cat_id_return);

            gr.query();

            if (!gr.next()) {

                alert("Please attach the Letter File to proceed further.");

                return false;

            }

I know 'gel' isn't supported by Service Portal so i did search in the community and found one solution to create a UI Script and call it in the catalog client script, but this also isn't working.

UI Script:

API Name: GlobalCatalogItemFunctions

function getSCAttachmentCount() {

  var length;

  try {

  length = angular.element("Copies/Reprints Request").scope().attachments.length;

  } catch(e) {

  length = -1;

  }

  return length;

}

Catalog Client Script

if (g_form.getValue('sbx_crr_requestType') == 'Manual Letter Generation for Address correction Requests') {

        try {

            var cat_id_return = gel('sysparm_item_guid').value;

            //alert('Happy '+cat_id_return);

            var gr = new GlideRecord("sys_attachment");

            gr.addQuery("table_name", "sc_cart_item");

            gr.addQuery("table_sys_id", cat_id_return);

            gr.query();

            if (!gr.next()) {

                alert("Please attach the Letter File to proceed further.");

                return false;

            }

        } catch (e) { //For Service Portal

            var count = getSCAttachmentCount();

            if (count <= 0) {

                alert('Please attach the Letter File to proceed further.');

                return false;

            }

        }

    }

Can someone please let me know how to achieve this solution.

Thanks,

Rooma

function onSubmit() {

    if (g_form.getValue('sbx_crr_requestType') == 'Manual Letter Generation for Address correction Requests') {

        try {

            var cat_id_return = g_form.getParameter("sysparm_item_guid");

            var gr = new GlideRecord("sys_attachment");

            gr.addQuery("table_name", "sc_cart_item");

            gr.addQuery("table_sys_id", cat_id_return);

            gr.query();

            if (!gr.next()) {
                alert("Attachment is mandatory");
                return false;
            }

        } catch (e) {

            if (this.document.getElementsByClassName('get-attachment').length == 0) {
                g_form.addErrorMessage(getMessage('Attachment is mandatory'));
                return false;

            }

        }
    }

this will work in both the UI Type

function onSubmit() {
    //Type appropriate comment here, and begin script below
    try {
        if (window == null && g_form.getValue('sbx_crr_requestType') == 'Manual Letter Generation for Address correction Requests') {
            // portal
            if (this.document.getElementsByClassName('get-attachment').length != 1) {
                alert('You must attach the completed form before submitting this request.');
                return false;
            }
        }
    } catch (ex) {
        // native view
        if (g_form.getValue('sbx_crr_requestType') == 'Manual Letter Generation for Address correction Requests') {
            var length = getCurrentAttachmentNumber();
            if (length != 1) {
                alert('You must attach the completed form before submitting this request.');
                return false;
            }
        }
    }
}
